BTW the French company OBEO were kind enough to give me a trial copy of their UML2ABAP product, it is only a protoype, but it works fine and I managed to generate some ABAP classes in my SAP system from a UML diagram. They will howvere be charging for this.
I have still nt managed to get the free equiavlent product UMAP to work, though I found the authirs email address today and asked him about it.
Cheersy Cheers
